System LEDs

The System LEDs indicate the switch’s status, independent of the port LEDs.

System LEDs Indication
Fault
(yellow LED)
• When lit, one or more of the ports has failed or the internal temperature has
exceeded acceptable levels.
• When flashing, all ports are operational but another error has occurred. Erro rs
appear in an event log. The level of error severity that will cause flash ing to start
can be controlled using the config sys fault command in the CLI. The default is
level 3, Critical.
Note: Whether lit or flashing, the switch will continue to operate. Switch
functionality may be impaired depending on the event that triggered the
Fault LED. Regardless of the cause, the switch requires immediate
attention.
